HORSESHOE.

This invention relates to certain new and useful improvements inhorseshoes, and has more particular reference to improved means fordetachably securing toe and heel calks of horseshoes in place so thatreplacement of worn out calks can be readily effected, and

. whereb the calks are effectivel and rigidly fixed in place for use.

A further object is to provide an improved horse shoe having detachabletoe and heel calks secured in place so as to present an extremely simpleand durable construction.

Other objects will appear as the nature of the invention is betterunderstood, and the same consists in the novel form, combination, andarrangement of parts hereinafter more fully described, shown in theaccompanying drawings, and claimed.

In the drawings, wherein like reference characters indicatecorresponding parts throughout the several viewsz- F ig. 1 is a bottomplan view of a horseshoe constructed in accordance with the presentinvention; v

Fig. 2 is a rear edge elevational view of the device shown in Fig. 1;

F 4 is a perspective view of one of the heel calks employed in the shoeshown in Figs. 1 and 2;

Fig. 5 is a side edge elevational View of the device shown in Fig. 1;

Fig. 7 is a transverse section taken substantially upon line 77 of Fig.6;

Fi 8' is a fragmentary section taken substantially upon line 88 of Fig.1;

Fig. 9 is a transverse section'taken upon line 99 of Fig. 1; and

Fig. 10 is a perspective view of the toe calk of the shoe shown in' Fig.1.

Referring more in detail to the drawings, the body 5 of the shoe is ofthe usual shape and has the ordinary arrangement of countersunk nailholes 6 for facilitating attachment of the shoe to the horses hoof. Theheel ends of the shoe are constructed alike for receiving the respectiveheel calks' 7, and each heel end is formed with depending parallelflanges 8 which form the side walls of a longitudinal socket forreceiving the shank 9 of the heel calk'i'. The rear ends of the flanges8 are connected by a transverse flange 10 which closes the rear end ofthe socket and forms an abutment for the rear end of the calk shank 5),whereby rearward displacement of the calk from the socket is positivelyprevented. The rear end of the shank 9 terminates forwardly of the rearside of the calk 7, as indicated at 11, so that the base of the calkflatly engages the lower' edge of the flange 10 for being effectivelybraced when in use. The inner side walls of the flanges 8' are undercutor beveled as at 12, and the sides of the shank 9. are beveled tosubstantially correspond therewith .so that the shank will snugly fit inthe socket and be frictionally retained therein after being driven intoplace by the use of a hammer or the like; The inclination of the bevelof the sid'es'of the shank 9 gradually increases in a rearward directionso that the shank is somewhat tapered smaller toward its rear end forfacilitating insertion of the rear end of the shank in the forward endof the socket preparatory to driving the calk in place. The transversewedge-shaped ground-engaging member of the heel calk is wider than andprojects beyond opposite sides of the rear end of the shank 9 so as torest flatly at its base against the lower edges of the rear end portionsof the flanges 8, and it will thus be seen that the calks are solidlyconnected to the heel ends of the shoe so that impacts thereon aretransmitted uniformly to the heel ends of the shoe. With the aboveconstruction, it is simply necessary to lock the heel calks againstforward displacement froin the sockets, and this is preferablyaccomplished by cross-pinning the calks as at 13, a cross-pin beinginserted in registering transverse openings in the forward ends of eachpair of flanges Sand the shank 9-of the cooperating calk, and the endsofthe pin being headed as at 14 by a riveting operation so as to beretained i'irplaee. This avoids the use of objectionable screws, and

The ends of the flanges 8 are connected at one end of the socket formedthereby, by a flange 10 which closes said end of the socket and forms anabutment for the adjacent end of the calk shank 9 ,whereby sidewisedisplacement of the calk 15 from the socket is positively prevented inone direction. In this instance, the calk body 15 extends parallel withthe shank 9 instead of transversely thereto as is the case with respectto the heel calk, and the base of the calk body 15 projects forwardly ofthe front side of the shank 9 so as to flatly engage the lower edge ofthe front one of the flanges 8 for being effectively braced when in use.The inner walls of the flanges 8 are beveled or undercut for snugreception of the beveled shank substantially as described above withrespect to the shank 9 and flanges 8. However, the sides of the shank 9are beveled at a uniform inclination from end to end instead of at agradually increasing inclination as is the case with the bevelling ofthe sides of the heel calk shanks 9. The toe calk is locked in placeagainst sidewise displacement in the other direction out of the socketby cross-pinning as indicated at 13 substantially in the same manner inwhich the heel calks are cross-pinned in place at 13- and as describedabove. that in all instances the cross-pin is provided near the open endof the calk shank receiving socket.

V In order to remove a calk it will simply be necessary to cut a headoff of one end of the cross-pin holding the same in place, whereupon thecalk may be driven out of the socket by the use of a hammer in anexpeditious manner. As indicated at 11 the shank 9 terminates short ofone end of the calk body 15 so that an end of the latter projects forflatly contacting with the lower edge of the flange 10*- at its base.This has a bracing action and at the same time per- .mits the toe calkto project equal distances to opposite sides of the longitudinal centerof the horseshoe body even though the flange 10 is employed.

From the foregoing description it is believed that the construction andoperation as well as the advantages of the present in V vention will bereadily understood and appreciated by those skilled in the art.

Minor changes may be made without de parting from the spirit andscope-of the invention as claimed. 7

It will be noted.

What I claim as new is In a horseshoe, a body provided upon its underside at one end with spaced flanges flush at their outer sides with theportion'of the body upon which they are formed, and a flange extendingtransversely between the rear ends of the fli'st-inentioned flanges andI of the body, and a calk comprising av body having downwardlyconverging inclined front and rear sides and a flat upper side, and ashank integral with. the calk body at the upper side of the body, theshank having a straight rear end perpendicular to the plane of the upper side of the body of the calk and spaced inwardly from the forwardside of said body to provide ashoulder portion, the said shank of thecalk having its opposite sidesbeveled and occupying upwardly divergingplanes, the said shank being fitted between the firstmentioned flangesupon the body of the horseshoe with the rear end oftheshank abuttingagainst the inner face of the secondfmentioned flange and with the uppersideof the calk body resting in contact with the under sides of thefirst and, second mentioned flanges, the said shank of the calkprojecting beyond the forward side of the calk body and having a beveledend inclined upwardly and rearwardly with respect to the under side ofthe body of the horseshoe and terminating at its lower portion flushwith the forward ends of the first-mentioned flanges upon the horseshoebody, the under side of the shank of the calk being inclined upwardlyand forwardly from the forward face of the calk body to the said beveledend the shank, the said shank and theflrste mentioned flanges near theirforward ends being provided with registering openings, and a securingelement secured through said openings.
